I use something like
\usepackage[pages=some]{background}
\backgroundsetup{%
firstpage=true,
contents={First Page},
placement=center
}
which sets the contents on the title page.
I now would like to add a (different) background on every following page.
Any ideas?
\AddToHook{shipout/background}{\put(<coordinate>){<stuff>}}
(see theltshipout
documentation).
